Could it be Delirium?

I can’t tell you how many unfortunate situations I have seen that could have been avoided if someone had asked “could it be delirium?” I have seen people committed to psychiatric facilities where they were treated for psychosis and I have seen people assigned long-term guardians because of what was a temporary alteration in consciousness caused by an episode of delirium. If you have ever seen people during a delirium it is not hard to understand how this can happen – they are often highly agitated, they may make outlandish statements with no basis in reality and they may even hallucinate. The symptoms may also fluctuate over a relatively short period of time which can add to the confusion. The problem is that a delirium is often a short-term situation resulting from a reversible condition like an infection, dehydration or an unintended response to a medication. There are three basic clues to look for if you think the person is suffering from delirium.

The first clue that it might be delirium is that the onset of the symptoms is fairly rapid. If a person over 55 years with no history of hallucinations starts talking about seeing bugs crawling on the wall it is appropriate to ask “could this be delirium?”

The second clue that it might be a delirium is that the person is not oriented to person, place and/or time – They can’t they tell you basic things about who they are, where they are or they can’t tell you the day, the month and/or the year? During a delirium a person will also have difficulty focusing their attention for sustained periods and will often have to have questions repeated for them – if they can respond at all.

The third clue that it might be delirium is the presence of significant changes in the person’s life. For example, recent onset of physical symptoms (especially those consistent with a Urinary Tract Infection), changes in medications, recent surgeries (deliriums are common after anesthesia), or changes in eating, drinking or sleeping patterns?

It is also important to understand that delirium is not mutually exclusive with any other condition – i.e. a person with any other condition (e.g., dementia, bipolar illness) can still experience delirium. A person with dementia who develops a delirium as the result of a Urinary Tract Infection (UTI) may be overlooked because the symptoms are assumed to be part of the progression of the dementia. The key is the timeframe for the onset of the worsening of symptoms. If there is any question, consult a physician – a test for a UTI is simple and it is usually treatable.

It is not wise, or helpful, to try to diagnose delirium and its primary cause on your own. The diagnosis of delirium is tricky, even for doctors, and that is why so many get overlooked. If the clues mentioned above are present, it is advisable to get the person to a doctor as soon as possible and to ask the doctor “could this be delirium?”
